Force Mupen64Plus to use the GLideN64 plugin instead (if installed) by launching with: mupen64plus --gfx mupen64plus-video-GLideN64.so Or, run it under XWayland: QT_QPA_PLATFORM=xcb mupen64plus The Nuclear Option: The Logger Mupen64Plus is polite enough to log errors, but on a crash, the terminal window vanishes too fast to read them.

Force Mupen64Plus to use the GLideN64 plugin instead

Don't give it a ROM yet. Just run the executable. Watch the text output. The crash will usually spit out a line like: ERROR: Could not load dynamic library: libGL.so.1 or Failed to init audio: No available audio device. And a blinking cursor
